I'm always looking for ways to streamline how I pack for a trip. Despite thinking I'm already a pretty good packer, I still think I can be better. Maybe you feel the same way.

Some of the best tips I've adopted into my travel routine are recommendations from friends and coworkers. So to help inspire you, I asked my Business Insider colleagues to share the things they always bring when they travel, and I got some interesting responses.

Some are seemingly random (an audio splitter), some are convenient (a pair of noise-cancelling headphones), and some you probably didn't realize you needed (a bottle of melatonin).

Check out our favorite travel picks below.

1/

An audio splitter

Amazon

Audio splitters are key for watching movies on iPad with significant other or friend. — Antonio Villas-Boas

An extra-long charging cable

A portable battery

Amazon

The sense of security a big portable battery gives you is invaluable. If I forget to charge my phone/tablet before leaving the hotel — and I always do — it's nice to know I'll still be safe to watch a movie on the flight, or have enough juice to call an Uber once I get off the bus. — Jeff Dunn

Noise-cancelling headphones

Amazon

These Bose headphones have a huge battery life — perfect for long hauls. They're so comfortable do you can even fall asleep despite their size, and since they're noise-cancelling headphones, they help combat aircraft noise. All of that, and the sound quality is excellent for all types of music. — Roddy Salazar

Streaming services

A portable Bluetooth speaker

Amazon

A Bluetooth speaker might seem like a superfluous thing to bring on a trip, but it was actually one of the most versatile gadgets I packed for my most recent vacation. I used it to help me sleep (see the next slide for more on that), liven up my showers (because it's also waterproof!), and for some entertainment when I was relaxing in my Airbnb at night. — Ellen Hoffman

A white noise app

Noisli

I've been using Noisli every night for about two years now, and I wouldn't go anywhere without it. Right before I'm ready to go to bed, I pair Noisli via Bluetooth to my portable Anker speaker when I'm away.

It proved particularly helpful during the London leg of my last trip; my first-floor Airbnb was located on a busy street and Noisli helped drown out the traffic outside. — Ellen Hoffman

A lint roller

A versatile scarf

Lululemon

I always bring my Vinyasa scarf from Lululemon when I travel. If you unbutton it, it turns into a wrap that makes a nice blanket while flying. You can also turn it into an infinity scarf or fold it up for a pillow. — Ashley Lutz

Ear plugs

Amazon

A good pair of earplugs! I sleep in hostels a lot when traveling to save money and meet people. If you know anything about hostels, there are people partying to all hours of the night and you are usually sharing a room with a few people. Earplugs make sure I can get a good night of sleep no matter what's going on around me. For my money, Mack's Originals are the best I've tried. They're comfortable to sleep with and very powerful. — Harrison Jacobs

A reusable water bottle

Amazon

I take my reusable water bottle with me everywhere I go! If I'm flying, I empty it before security and fill it up at a drinking fountain inside. I absolutely REFUSE to pay $5 for bottled water. Not to mention, it's better for the environment as well.

I've been using the classic Nalgene bottle for over a decade and have never found another water bottle that I like better (and I've tried all the trendy ones). — Emmie Martin

A multi-port wall charger

A hanging toiletry bag

Amazon

I always travel with a hanging toiletry bag to store my jewelry. A tip my mom gave me and it works like a charm.

The small zippered compartments are perfect. Little compartments are great to divide delicate pieces that would potentially tangle with other pieces of jewelry. Store your jewelry in this, hang it on a door when you get to your destination, and viola! — Marri Milcarek

Sunscreen

Sanitizing wipes

Walgreens

To avoid getting sick when I fly, I buy individual packages of cleaning wipes. I wipe down the seat, the tray table, and the remote for the seat screen if there is one. I read an article many years ago about how disgusting your airline tray table is as well as the surroundings, and to avoid getting sick, this is one thing you can do to protect yourself. — Cindy Pabst

An aromatic stress oil

Amazon

I'm a nervous flyer, so I pack my carry-on with products that will keep me comfortable and calm. As soon as I find my seat, I rub Tata Harper's aromatic stress oils onto my pulse points and take a few deep breaths. It is a splurge, but this little bottle will last you years. And if you're terrified of flying like me, having some peace of mind is priceless. — Kelsey Mulvey

A perfume dispenser
